Introducing the Switch
The HP ProCurve 2520G-PoE Switches are multiport switches that can be used
to build high-performance switched workgroup networks. These switches are
store-and-forward devices that offer low latency for high-speed networking.
The 2520G-PoE switches also support Power over Ethernet (PoE)
technologies.
Throughout this manual, these switches will be referred to as the Switch
2520G-8-PoE and the Switch 2520G-24-PoE.
■ The Switch 2520G-8-PoE has 8 auto-sensing 10/100/1000Base-T RJ-45
ports with two Gigabit Uplink dual-personality ports (ports 9 and 10).
■ The Switch 2520G-24-PoE has 24 auto-sensing 10/100/1000Base-T RJ-45
ports, four of which are dual-personality ports (ports 21 through 24).
■ Power-over-Ethernet or PoE power - Both 2520G-PoE switches
support PoE technology, which allows IP telephones, wireless LAN
Access Points and other appliances to receive power as well as data over
existing LAN cabling, without needing to modify the existing Ethernet
infrastructure. The Switch 2520G-24-PoE is designed with an internal PoE
power supply capable of providing 195 watts of PoE power (67 watts on
the Switch 2520G-8-PoE). Each Switch port can provide up to 15.4 watts
(or 7.5 watts if all ports are used) of PoE power to connected devices. For
further information regarding PoE power, see the PoE Planning and
Implementation Guide, which is on the ProCurve Web site at
www.hp.com/go/procurve/manuals.
